The following parameters may be viewed or modified:
Parameter Description
VLAN ID This is the VLAN ID that, along with th e VLAN Name, identif ies the VLAN for which
to modify the MLD Snooping Settings.
VLAN Name This is the VLAN N ame that, along with th e VLAN ID, identifies t he VLAN for which
to modify the MLD Snooping Settings.
Query Expiry Time Displays the query expiry time in seconds.
Query Interval (1-65535 sec) Allows the entry of a value between 1 and 65535 seconds, with a default of 125
seconds. This specifies the length of time between sending IGMP queries .
Max Response Time
(1-25 sec) This determines the maximum amount of time in seconds allowed to wait for a
response for MLD port listeners. The Max Response Time field allows an en try
between 1 and 25 (seconds). Default = 10.
Robustness Value (1-255) Provides fine-tuning to allow for expected packet loss on a subnet. The user may
choose a value between 1 and 255 with a default setting of 2. If a subnet is ex p e ct ed
to be lossy, the user may wish to increase this interval.
Last Listener Query Interval
(1-25 sec) Specifies the maximum amount of time between group-specific quer y messages,
including those sent in response to leave group messages. A value between 1 and
25. The default is 1 second.
Data Driven Group Expiry
Time (1-65535) Specifies the data driven group expiry, in seconds. T he user may specify a time
between 1 and 65535 with a default setting of 260 seconds.
Querier State The default is Disabled. If the field displays “Disabled”, it will always be in M LD-
Snooping non-querier state.
Fast Done Used to enable or disable the fast done state of the switch. T his field is disab led by
default.
State Used to enable or disable MLD snooping for the specified VL AN. This field is
Disabled by default.
Report Suppression Used to enable or disable MLD Snooping report suppression for the specified VLAN.
Data Driven Learning State If the state is Enabled, it allows the switch to be selected as a MLD Querier (sends
MLD query packets). It the state is Disabled, then the switch cannot play the role as
a querier.
Data Driven Learning Aged
Out Used to Enable or Disable the aging out of MLD Snooping data driven learning for
the specified VLAN.
Version Used to configure the version of MLD used on switch. The default value is 2.
Querier Role This read-only field describes the current querier state of the Switch, whether
Querier, which will send out Multicast Listener Query Messages to links, or Non-
Querier, which will not send out Multicast Listener Query Messages.
